An apparatus for producing holes in dielectric workpieces in the form of thin sheets and substrates, in particular of glass or glass-like materials and semiconductors is provided. The apparatus includes individual high-voltage electrodes that are symmetrically arranged on an electrode holder around the hole to be produced in the workpiece. The apparatus also includes individual counter electrodes that are arranged on a counter electrode holder. The electrodes and counter electrodes can be connected in a permutating manner to a high-voltage source for the discharge of high-voltage flashovers.

Generation of holes using multiple electrodes

In order to improve the energy balance of an HID lamp, the quartz burner, preferably the inside thereof, is coated with a UV reflecting layer system by alternatingly applying amorphous thin layers made at least of titanium oxide and silicon oxide having the respective general stoichiometry TiOand SiOby means of a plasma impulse chemical vapor deposition (PICVD) method at a high power density and increased substrate temperatures ranging from 100&#xb0; to 400&#xb0; C., using small growth rates ranging from 1 nm/sec to 100 nm/sec so as to form an interference layer system having a thickness of less than 1200 nm and a minimized UV-active defective spot rate ranging from 0.1 to 1 percent.

Method for coating the quartz burner of an HID lamp

The method for coating plural surfaces on multiple sides of a substrate, especially a lens, includes launching microwave outputs into a microwave reactor at respective microwave launch sites; selecting respective microwave outputs to be greater than or equal to thresholds at which corresponding plasmas having a reduced permeability to microwave radiation arise in the microwave reactor; setting distances between the plural surfaces and microwave launch sites greater than microwave penetrations depths in the plasmas; placing respective dielectric tuning elements in microwave fields formed from the microwave outputs at the launch sites; and adapting the shapes of the dielectric tuning elements to the plural surfaces to be coated, so that plasma inhomogeneities are corrected and coatings with a uniformity of &#xb1;1% are formed on the plural surfaces.

Method and device for coating substrates

This invention relates to optical, preferably ophthalmic lenses with a body made of plastic, in particular for spectacle glasses, and the plastic incorporates cycloolefinic polymers and the plastic body is coated with a transparent coating resistant to corrosion. Another object of this invention is a process for the production of these lenses. The lenses according to the invention are especially resistant to greases, sweat and/or solvents.
